THE KOSCIUSCO – LOSS OF AN APPRENTICE.
The Sydney-owned barque Kosciusko arrived yesterday from Gothenburg. She reports a sad accident during the voyage. One of the apprentices, Albert Bear, a son of Mr. Superintendent Bear, of the Metropolitan Fire Brigade, when in the act of loosening the main topgallant sail fell into the sea and was drowned. He was never seen after passing the ship's quarter either from the deck or aloft, but sunk at once. The ship at the time was running before a fresh gale and a heavy sea. The main topsail halyards were let go and the foresail let fly at once and the ship rounded to at some risk, but no one caught sight of him ; indeed, had he been seen, it is doubtful if a boat could have lived to reach him. He must have fallen 140ft. The accident caused quite a gloom amongst the crew, the young follow being liked by everyone on board for his manly qualities. " There was not a soul of us," said one of the ship's company, yesterday, "who wouldn't have jumped overboard to pick him up, blow or no blow, had we caught sight of the lad." He was a bright, good lad, and the makings of a real sailor." The report of his loss on the vessel's arrival here caused extreme regret, and came as an awful shock to his relatives. The barque sailed from Gothenburg on the 11th May, and took departure from the Lizard on the 27th. Had strong head winds across the North Sea and down Channel. Got the N.E. trades in lat. 30' W. From Lat. 9' to 4' and 19' W. had strong S.W. monsoon, and crossed the equator in 20' W. Thence to 15' S. had strong southerly winds, having to tack ship several times to keep off the Brazilian coast. and the remainder of the voyage to Cape Otway experienced fresh to very hard gales. Used oil bags when running in the heaviest of the gales with good results. Saw ice three different times between 38' and 41 S. and 20' and 72' E. Also passed a derelict, with part of a mast standing, in lat. 28' N. and 24' W. Spoke the barque Columbia, bound to Valparaiso, in 4' N. The Kosciusko is to Mr. Alexander Burns.
